Seems like the RC domains have been blocked in China Mainland.

Me too, I currently have a large number of members looking for me, their app is now unusable, my members are integrated with RevenueCat!!!!!!!!! How can I solve this??? RevenueCat

Hello, 

Cesar from RevenueCat here.

We are aware of the situation and the team is looking for solutions to mitigate it.

 

We recommend setting the `proxyURL` property to `https://api.rc-backup.com/` before initializing the RevenueCat SDK. Make sure this happens before configuring the SDK:

We are working on finding a more permanent solution.

https://www.revenuecat.com/docs/getting-started/configuring-sdk#configuration-for-users-in-mainland-china

Purchases.proxyURL = URL(string: "https://api.rc-backup.com/")!

​@Cesar - is it safe to just set this for all users, or we need to only do this for users in mainland China?

​@Cesar Does the proxy url work for api v1 and v2?

It is safe to set this for all users, and it does work for both API versions

The SDK works fine, and the APIs were also working, but since yesterday the APIs have suddenly stopped working for me. Specifically I get this 400 bad request error: 
```

{

"doc_url": "https://errors.rev.cat/parameter-error",

"message": "None",

"object": "error",

"retryable": false,

"type": "parameter_error"

}
```

An identical Api call sent to revenuecat.com instead of rc-backup.com works, but only outside of China.
